To all whom it may concern:

' Be it known thatI,JosE1 n HENRY Oseoon, of Peabody, in the county of Essex and State of Massachusetts,have invented certain new and useful Improvements in Printers Inking-Rollers; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

My invention consists in an improved composition for printers inking-rollers, and for kindred or other purposes.

The materials from which 1 make the composition are dextrine and glue or gelatine. These are mixed together in suitable proportions-say about one part of dextrine to two parts of glue or gelatineand in a proper man- (No specimens.)

The composition, whether with or without such additional substance or substances, may be used for other purposes than inking-rollers but in every case the dextrine is to be compounded with glue or gelatine, this forming the leading feature of my invention.

The proportions may also vary to meet any variance in the quality of the respective ingredients employed.

The dextrine may be that made from potatostarch, corn-starch, wheat, or other article, and it gives to the composition an excellent"tack or suction th at is, the property of carrying ink, and without causing it to shrink or crack. At the same time it gives body or density and makes it tough and strong.

I claim The described composition for printers ink- JOSEPH H. oseoon.
